Dear Sri Sundaresh and resp vriti farms,
There are several methods in propagating the mother plants. In that, ghootis, layering, air layering, Tissue culture, grafting, sayaan etc are in practice. In all the above the Tissue culture plants are of the latest technology, which is universally accepted and an universally accepted/following method. The mother plants in this system are well studied for disease freeness , good charectors, and guaranteed for their quality, healthiness and disease free. I think, that we have to welcome the standard, universally accepted technologies.
One fact is true that, graftings, air layering saplings are much cheaper when compared to grafts and mainly Tissue culture saplings. To the extent possible, we should encourage and use tissue culture technology to the extent possible, as we can achieve good results with TC plants, as it is a successful universal technology.
I have visited several, very more number of pomegranate farms, used air layers, ghootis, grafts, Tissue plants, from several years and undoubtedly, observed that TC pomegranate plants are giving good results and they are the best, and trust worthy.
Any how, the above is my observations and opinion and it may be considered or not, left to the discretion of our fellow farmers.
With best wishes, g.p.rao, farmer
